Technical Field
[0001] The utility model relates to the technical field of pipeline construction, in particular to a water pipeline construction docking device. Background Art
[0002] A water pipeline is a system of pipes and channels that transport water from a distant water source to the water use location. Prestressed concrete cylinder pipe is a composite pipe with a complex structure, mainly used in large-scale water transmission projects and municipal water supply systems. During the assembly and docking process of prestressed concrete cylinder pipe, the external pulling method and the internal pulling method are commonly used for pulling and docking. The external pulling method is mainly used for pipes with smaller diameters, while the internal pulling method is mainly used for pipes with larger diameters. The internal pulling method inserts a crossbeam into the gap between the sockets of the two installed sections of pipes, and uses wire rope and channel steel crossbeams (or hooks) to fix the pipe to be installed. Then, a hand winch (lever winch) is used on the inside of the pipe to gradually tighten the pipe to achieve the socket docking and complete the pipe installation.
[0003] Although the docking device in the prior art has many benefits when used, it still has the following problems: it only uses a pair of beams and wire ropes for pulling, which results in an unstable pulling direction of the pipes to be installed, affecting the docking accuracy between the pipes. The staff needs to repeatedly adjust the pulling direction of the pipes to be installed, which affects the docking efficiency of the pipes. Utility Model Content

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a water pipeline construction docking device described in the utility model includes a first crossbeam 1, a second crossbeam 2 and a drive shaft 15. The second crossbeam 2 is provided on the outer wall of one side of the first crossbeam 1, and a clamping sleeve 11 is installed on the outer wall of one side of the first crossbeam 1 and the second crossbeam 2. A rotating shaft 12 is rotatably installed inside the clamping sleeve 11, and a sleeve 13 is installed on the outer wall of one end of the rotating shaft 12. A lifting ring 21 is installed on the outer walls of both sides of the first crossbeam 1 and the second crossbeam 2. The drive shaft 15 is rotatably installed inside the first crossbeam 1, and a screw 22 is rotatably installed inside the second crossbeam 2.
[0028] During use, the staff connects to the connecting block 16 through a wrench or a pistol drill, thereby driving the drive shaft 15 and the screw 22 to rotate in a circle, and the second beam 2 can move horizontally relative to each other through the rotation of the screw 22, until the first beam 1 and the second beam 2 squeeze the protective pad 25 and contact the inner wall of the interface of the pipe to be installed, and the external hand hoist pulls the wire rope, and the wire rope pulls the first beam 1 and the second beam 2 through the lifting ring 21 and the hook 23, thereby pulling the pipe to be installed toward the direction of the installed pipe.
[0029] For the initial stabilization of the device, for example, Figure 1 As shown, the inner thread of the sleeve 13 is connected to the support rod 14, and the outer wall of one end of the support rod 14 is designed in a conical shape.
[0030] When in use, one end of the support rod 14 is in contact with the ground, and can support the first beam 1 and the second beam 2 to ensure that the initial positions of the first beam 1 and the second beam 2 are stable.
[0031] In order to drive the pipeline to move, for example, Figure 2 As shown, a hook 23 is provided inside the lifting ring 21, and a steel wire rope is installed on the outer wall of one end of the hook 23 away from the lifting ring 21.
[0032] When in use, the wire rope is connected to the external hand chain hoist, so that the first crossbeam 1 and the second crossbeam 2 can be pulled to move through the lifting ring 21 and the hook 23.
[0033] To protect the pipeline, for example, Figure 2 As shown, protective pads 25 are fixed to the outer walls of both sides of the first crossbeam 1 and the second crossbeam 2 , and the outer walls of the protective pads 25 are designed in an arc shape.
[0034] When in use, the first crossbeam 1 and the second crossbeam 2 contact the inner wall of the interface of the pipe to be installed through the protective pad 25. The protective pad 25 can protect the inner wall of the interface of the pipe to be installed, preventing the first crossbeam 1 and the second crossbeam 2 from causing damage to the inner wall of the interface of the pipe to be installed.
[0035] In order to drive the driving shaft 15 to rotate, for example, Figure 3 As shown, a connecting block 16 is installed on the outer wall of one end of the driving shaft 15, and the outer wall of the connecting block 16 is designed in a rectangular shape.
[0036] During use, an external wrench or pistol drill can be connected to the connecting block 16 , thereby driving the driving shaft 15 to rotate in a circular motion.
[0037] In order to adjust the distance between the first beam 1 and the second beam 2, for example, Figure 1As shown, couplings 24 are installed on the outer walls of the screw rod 22 and the drive shaft 15 on the opposite side. Bolts distributed in a circular array are arranged inside the couplings 24, and the couplings 24 are connected by bolts.
[0038] During use, the coupling 24 can be connected by bolts, thereby ensuring the stability of the connection between the screw rod 22 and the drive shaft 15 and ensuring that the screw rod 22 can rotate along with the drive shaft 15 .
[0039] When the utility model is in use, the staff manually takes the hook 23 and connects it to the lifting ring 21, and the staff uses the external lifting device to place the first crossbeam 1 and the second crossbeam 2 respectively inside the interface of the pipe to be installed;
[0040] The staff rotates the support rod 14 to fix the support rod 14 inside the sleeve 13. The support rod 14 rotates through the rotating shaft 12 and the clamping sleeve 11, and the cone of the support rod 14 supports the first beam 1 and the second beam 2 to maintain the position stability of the first beam 1 and the second beam 2.
[0041] The staff manually turns the bolts to connect the coupling 24, thereby connecting the drive shaft 15 and the screw 22;
[0042] The worker connects the connecting block 16 with a wrench or a pistol drill, thereby driving the drive shaft 15 and the screw 22 to rotate in a circular manner. Since the second crossbeam 2 is attached to the inner wall of the pipe interface to be installed, the second crossbeam 2 can be moved horizontally relative to it by the rotation of the screw 22 until the first crossbeam 1 and the second crossbeam 2 both squeeze the protective pad 25 and contact the inner wall of the pipe interface to be installed.
[0043] The staff pulls the wire rope through the external hand hoist, and the wire rope pulls the first beam 1 and the second beam 2 through the ring 21 and the hook 23, thereby pulling the pipe to be installed toward the installed pipe until the pipes are connected.
